With Penrith, I'm sure the 4 jerseys from this year will stay the same in 2012 - black home, white ribbon away (the teal jersey has effectively now been shafted), the '91 heritage and pink jersey. There is also a members jersey, limited to 300, based on the away jersey and similar to what the Sharks have done in previous years, with members names on it.
On the sponsorship front, there's talk that Sanyo may not be back next year. It's more to do with the brand itself being bought out by Panasonic, so they could be the sponsor next year, or it could be something completely different. But everything else will probably stay the same, with ISC being the manufacturer, Onsite Cleaning on the sleeve, Tony Feguson on the lower back, and Abcoe and Host Plus on the shorts. HIT (top back) I think was a Sanyo company, so that may change.
